Definitions

  • the present invention relates to a button for clothing.
  • the invention can be used in the textile industry for manufacturing items of clothing.
  • press-studs are widely used that are made of metal and/or plastic material, and are used in particular on garments made of denim, such as jeans, jackets or shirts.
  • Automatic buttons are made up of two complementary elements arranged on two separate flaps of the item of clothing, and can be coupled and decoupled elastically.
  • buttons In these buttons, the pressure is exerted between the two complementary elements.
  • Tack buttons usually have:
  • the shaft of the tack is press-fitted into the tubular shank of the mushroom-shaped component, after having been passed through the flap.
  • the shaft of the tack/rivet and the shank of the mushroom-shaped component have such shapes and dimensions as to produce a mutual interference after the former is inserted into the latter, generating a stable and non-removable coupling.
  • press-studs which have, instead of a tack/rivet, a screw with a threaded shaft which is inserted by pressure, or by screwing, into the shank of the mushroom-shaped component, and can be removed from it by unscrewing it from the mushroom-shaped component.
  • buttons Furthermore, with such a button the operation to remove the buttons is long and inconvenient, especially when it is necessary to remove more than one button.
  • the aim of the present invention is to provide a button for clothing which is capable of improving the prior art in one or more of the above-mentioned aspects.
  • an object of the invention is to provide a button for clothing that can be removed from the item of clothing to which it is applied without the aid of tools.
  • Another object of the invention is to provide a button for clothing that can be removed from the item of clothing to which it is applied more easily and rapidly than similar, conventional buttons.
  • a further object of the invention is to provide a button for clothing that can be completely and easily recycled.
  • Another object of the present invention is to overcome the drawbacks of the prior art in a different manner to any existing solutions.
